In a statement, the USPCA board said the dismissal related to aspects of Mr Philpott's management of the organisation and followed a review by an independent consultant, a full disciplinary hearing and exhaustive appeal process.

An interim manager has been in place for a number of months.

USPCA chairman Helen Wilson said the day-to-day work of the charity continued and said staff had "worked tirelessly to ensure that the service to animals has remained exemplary during a very difficult time".

Mr Philpott was particularly outspoken on a number of animal welfare issues including dog fighting and badger baiting.
